Bali cattle () are an Indonesian's native cattle breed that distributed in Asia to Australia. The scientific literature on these cattle is scarce. The growth hormone (GH) of Bali cattle is investigated from three separated islands, namely, Bali, Nusa Penida, and Sumbawa.
Forty plasma samples were collected from each island, and the GH was measured using a commercial enzyme-linked immunosorbent assay kit. The data were analyzed based on the origin, sex, and cattle raising practices.
We found that the GH level (bovine GH [BGH]) of animal kept in stall 1.72±0.70 µg/ml was higher than free-grazing animal 1.27±0.81 µg/ml. The GH level was lower in female (1.22±0.62 µg/ml) compared to male animals (1.77±0.83 µg/ml).
We conclude that the level of BGH in Bali cattle was low and statistically equal from all origins. The different level was related to sex and management practices. Further validation is needed through observing the growth rate following BGH administration and discovering the inbreeding coefficient of the animal in Indonesia.
巴厘牛（）是一种原产于印度尼西亚的牛品种，分布于从亚洲到澳大利亚的地区。关于这些牛的科学文献稀少。本研究从巴厘岛、努沙佩尼达岛和松巴哇岛这三个不同的岛屿对巴厘牛的生长激素（GH）进行了调查。
从每个岛屿采集了40份血浆样本，并使用商用酶联免疫吸附测定试剂盒测量生长激素。根据牛的来源、性别和饲养方式对数据进行分析。
我们发现，圈养动物的生长激素水平（牛生长激素[BGH]）为1.72±0.70微克/毫升，高于自由放牧动物的1.27±0.81微克/毫升。与雄性动物（1.77±0.83微克/毫升）相比，雌性动物的生长激素水平较低（1.22±0.62微克/毫升）。
我们得出结论，巴厘牛的BGH水平较低，且在所有来源中在统计学上无差异。不同的水平与性别和管理方式有关。需要通过观察注射BGH后的生长速度以及确定印度尼西亚这些动物的近亲繁殖系数来进行进一步验证。
